Description

本発明は、並設されたワイヤ列で被加工物を放電によりスライスするワイヤ放電加工装置であって、前記ワイヤ列を同じ方向に走行させる走行手段と、前記被加工物を前記放電によりスライスする場合に、角状である被加工物の二辺が、前記ワイヤ列方向と交差し、かつ前記ワイヤ列と対向するように前記被加工物を配置する配置手段と、を備え、前記被加工物のスライスを開始する前には、前記配置手段が前記ワイヤ列から前記二辺における一方がより遠くなるように前記被加工物を配置して前記被加工物と前記ワイヤ列との極間を保持し、前記被加工物のスライスを開始したあとに、前記配置手段が、前記ワイヤ列の面に対する前記被加工物の加工面がほぼ平行になるように前記被加工物の配置を変更して前記被加工物と前記ワイヤ列との極間を保持することを特徴とする。 The present invention relates to a discharge by slicing to Ruwa ear discharge machine a workpiece in juxtaposed sum ear column, a traveling means for traveling before Kiwa unpleasant column in the same direction, the workpiece when sliced by the discharge, two sides of a square-shaped workpiece, the cross wire column, and provided with a locating means for the placing workpiece to the wire row facing the before starting the slice of the workpiece, the positioning means is the word before the tire column by placing one of the workpiece to be more distant in the two sides Symbol workpiece before Symbol After holding the gap with the wire row and starting slicing the work piece, the placement means is arranged so that the work surface of the work piece is substantially parallel to the surface of the wire row. The arrangement of the object is changed to change the workpiece and the wire row Characterized by holding the machining gap.

また、前記被加工物のスライスを開始する前には、前記配置手段が前記二辺においてより遠くなる一方を、前記走行するワイヤ列が前記被加工物に進行する側にして前記被加工物と前記ワイヤ列との極間を保持することを特徴とする。 Further, the before starting a slice of the workpiece, one of said locating means is farther in front Symbol two sides, front and the side of the travel to Ruwa unpleasant column progresses before Symbol workpiece serial, characterized in that for holding the machining gap between the workpiece and the prior SL wire array.

また、前記被加工物のスライスを開始する前に前記配置手段により保持されている前記被加工物の二辺における一方とその他方との前記ワイヤ列までの極間距離の差が、ワイヤの直径の２倍以上あるいは１ｍｍ以上のいずれか一方を満たしていることを特徴とする。 Also, the difference in the inter-electrode distance until verge ear columns of one of the two sides of the workpiece held by said locating means prior to starting a slice of the workpiece and its other is, wire It is characterized in that either one of the diameters of 2 mm or more or 1 mm or more is satisfied.
